During the two weeks Williams is scheduled to be out, the Blazers will play at least eight games, including Friday's matchup against New Orleans that concludes a five-game road trip that started with four losses. The two-week stretch also includes another five-game trip, with the two weeks ending during a back-to-back at Atlanta and Chicago.

Williams leads all Blazers reserves in scoring at 9.4 points, and his 269 assists lead all bench players in the NBA. The Blazers are 24-5 when Williams scores 10 points or more.

With Williams out, Blazers coach Terry Stotts tapped veteran Earl Watson for 10 minutes, 42 seconds against the Spurs. Watson made an immediate impact when he entered Wednesday's game late in the first quarter and got assists on three consecutive Blazers baskets in a span of 1 minute, 53 minutes. Watson did not score.

Starting point guard Damian Lillard played 39 minutes, 38 seconds against the Spurs and finished with a team-high 23 points. That came a night after Lillard played 38:38 and scored 32 points against Memphis. In that game, Williams was injured in the second quarter after playing 11:10 and getting four points and three assists.
